LOUISVILLE, Ky --- Michael Dyer may be coming to Louisville, but Cardinals first-string running back Dominique Brown doesn't seem too concerned. 

While Charlie Strong and select players were in Newport, Rhode Island Monday for American Athletic Conference media day activities, speculation continued to grow about Louisville adding Dyer to the roster.

That afternoon, this was posted on Brown's Twitter account:

"Man everyone wants to hyped this guy up all I kno is my boys and I AINT GOT NO WORRIES man! and thats real talk @SenoriseP @BrandonRadcliff"

@SenoriseP and @BrandonRadcliff are Senorise Perry and Brandon Radcliff, two other running backs on the Louisville football team.

Brown, a junior, was listed as a starting running back after spring practices and as a co-starter with Perry in the pre-fall camp media guide. Perry is a senior and is coming off a torn ACL.

Radcliff, a redshirt freshman, is listed 4th, behind sophomore Corvin Lamb.

The Cardinals first practice is Tuesday. Let the backfield competition begin.
